Jean-Philippe Brucker c7777236dd ACPI/IORT: Fix rc_dma_get_range()
When executed for a PCI_ROOT_COMPLEX type, iort_match_node_callback()
expects the opaque pointer argument to be a PCI bus device. At the
moment rc_dma_get_range() passes the PCI endpoint instead of the bus,
and we've been lucky to have pci_domain_nr(ptr) return 0 instead of
crashing. Pass the bus device to iort_scan_node().

Fixes: 5ac65e8c89 ("ACPI/IORT: Support address size limit for root complexes")
